METHOD OF MAKING NON-SLIPPING TREADS, PAVING, 86C- SPECIFIGATION formingpart of Letters Patent No. 659,815, dated October 16, 1900.

Application filed March 28, 1900. Serial No. 10.461. (No model.)

To (bl/Z 1071 0717, it nttty concern:

Be it known that I, FREDERICK WILLIAM HUESTIS, a citizen of the UnitedStates, residing at Newton, in the county of Middlesex andStateofMassachusetts,haveinvented certain new and useful Improvements inMethods of Making Non-Slipping Treads, Paving, &c., of which thefollowing is a specification, reference being had therein to theaccompa- IO nying drawings.

Reference being had to the accompanying d rawings, Figure 1 is aperspective view show ing a plurality of strips of pliable material(lead, for example) united at end portions with one form of base-plate,the other portions of the strips being in position to illustrate theirassemblage in parallelism. Fig; 2 is a sectional view illustrating thecompleted article of manufacture and is taken at line 2 2 of Fig. 1.

The object of my invention is to produce an economical andpractically-effective method of uniting the so-called non-slippingmaterial and hard-metal base-plates of so-called non-slipping treads,pavements, and the like.

In accordance with my present invention I first assemble a plurality ofstrips of the non-slipping material, preferably lead, in parallelismwith each other at distances apart and in line with spaces between theprojecting wear or tread surfaces of the baseplate, the strips being ofa shape which requires alteration in order that the strips may fit andfill the said spaces. I next transform said strips under a homingpressure into shapes that fit and fill said spaces, and during suchtransformation and pressure I bend inwardly upon each strip the upturnedWearsurfaces, which may be either interrupted, as in United StatesLetters Patent No. 638, 666, of December 5, 1899, or continuous, as inUnited States Letters Patent No. 481,702, of August 30, 1882, forexamples.

My new method maybe practiced by a great variety of either hand or powerdriven apparatus or machinery, and in my application, Serial No. 10,462,of even date, I describe forms of power-driven machines suitable for thepurpose.

In the accompanying drawings, at is the base-plate, and a itsupwardly-turned treadsurfaces or wear-points, which are formed inparallel rows. The plate a is preferably perforated at a along everyother space or lane a between thetread-surfaces, and the strips 1), oflead or other suitable non-slipping ma terial, are combined with theplate by anchoring them between rows of tread-surfaces, preferably, butnot necessarily, leaving every other lane vacant. The strips 1), beingarranged in parallelism and in line with the lanes to be filled, areforced simultaneously under my new method into the lanes, each stripbeing of a shape which requires expansion in order to make it fit andfill the lane in which it is mounted. The homing pressure on the stripswhen the plate has perforations, as in the form shown, not onlytransforms the strips in shape, so as to make them fit and fill thelanes, but also forces the lead through the porferations, so it becomesanchored on the back or under side of the plate. The pressure whichtransforms the lead strips and forces each strip home is utilized, inaccordance with my invention, to cant the Wear-surfaces inwardly, asshown in Fig.

2, upon the strips.

\Vhat I claim is- 1. The herein-described improvomentin the art ofmaking non-slipping treads, paving and the like, said improvementconsisting in the method of first assembling a plurality of pliablestrips in parallelism and in line with spaces between rows oftread-surfaces which project from a base-plate; and secondly, insimultaneously transforming and homing the strips in said spaces andcanting the opposing wear-surfaces upon intermediate strips.

2. The herein-describedimprovementin the art of making non-slippingtreads, paving and the like, said improvement consistingin the method offirst assembling a plurality of pliable strips in parallelism and inline with spaces between rows of tread-surfaces which 5 project from abase-plate; and, secondly, in simultaneously transforming and homing thestrips in said spaces.

In testimony whereof I affix my signature in presence of two witnesses.
